"Welcome to the world of science!"  When Yatori was 9 years old, she was sent to study with the general Bada Sankrein, and met a young boy her age, Ikta.  The world he shows her is new and exciting, like nothing she's ever seen.
Anything that doesn't end in us 
both going home is equally bad.
أي شيء لا ينتهي بعودة كِلينا إلى المنزل
فهو سيّئ
Wenn wir es nicht beide schaffen,
ist das doch sinnlos!
Uno o dos muertos es igual de malo.
Uno o dos muertos es igual de malo.
C’est inacceptable
qu’un de nous y passe !
Tutte le soluzioni che non salvino entrambi 
sono ugualmente pessime.
Tudo que não for "os dois voltaram
 para casa" é a pior hipótese!
Всё, что не заканчивается идущими домой нами,
 исключительно плохо.
